IR35 Considerations
What Is IR35?
IR35 (off-payroll working rules) determines whether a contractor should be taxed as an employee for a specific engagement.
Who Determines Status?
| Client Size | Who Decides |
|---|---|
| Small private sector | Contractor's company |
| Medium/large private sector | Client |
| Public sector | Client |
Small company definition: Meets 2 of 3 criteria:
- Turnover under £10.2m
- Balance sheet under £5.1m
- Fewer than 50 employees
Inside IR35 Consequences
If inside IR35:
- Tax and NI deducted at source
- Contractor receives less net pay
- Potential IR35 tax liability on historical payments
Key IR35 Indicators
Inside IR35 (employment-like):
- Client controls how, when, where work is done
- Consultant must do work personally
- Ongoing, mutually-obligated relationship
- Paid fixed salary regardless of output
- Uses client's equipment
- Works exclusively for one client
Outside IR35 (genuine business):
- Consultant controls working methods
- Right to send capable substitute
- No guaranteed work between projects
- Paid by results/project
- Uses own equipment
- Multiple clients
Status Determination Statement
For medium/large clients, the client must:
- Make reasonable care determination
- Provide Status Determination Statement (SDS) to contractor
- Provide SDS to any agency in the chain
- Be prepared to justify determination
Genuine Consultancy Indicators
To support outside IR35 status:
- Multiple clients - don't work exclusively for one
- Substitution clause - include and be prepared to use
- Project-based - clear deliverables, not just time
- Own equipment - use your own laptop, software
- Business presence - website, marketing, other clients
- Financial risk - fixed price with risk of loss
- No integration - don't attend all staff meetings
Employment Rights
Genuine consultants are not entitled to:
- Holiday pay
- Sick pay
- Pension auto-enrolment
- Unfair dismissal protection
- Redundancy pay
- Minimum wage (they set their fees)
However, if the relationship is actually employment, these rights apply regardless of what the contract says.

Frequently Asked Questions
- What is the difference between a consultant and an employee?
- A genuine consultant is self-employed, provides services to multiple clients, has control over how they work, can send substitutes, and bears financial risk. Employees work under the employer's control, cannot send substitutes, and receive regular pay regardless of profit.
- What is IR35?
- IR35 is legislation that determines whether a contractor should be taxed as an employee. If the relationship would be employment if the contract was direct, the contractor falls 'inside IR35' and pays employment taxes.
- Who determines IR35 status?
- For medium and large private sector clients (and all public sector clients), the client must make the IR35 determination. For small private sector clients, the contractor's limited company makes the determination.
